The IESO engages with local and regional communities to seek input to help inform planning activities. Learn more about engagement on the current planning cycle.
The KWCG region is located to the west of the Greater Toronto area in southwestern Ontario. The region includes the municipalities of Kitchener, Waterloo, Cambridge and Guelph, as well as portions of Perth and Wellington counties and the townships of Wellesley, Woolwich, Wilmot, North Dumfries and the Region of Waterloo.
The area's electricity demand is a mix of residential, commercial and industrial loads, and includes diverse economic activities such as major educational institutions and automobile manufacturing. The KWCG area is expected to achieve substantial continued population growth over the next 20 years.
A Technical Working Group consisting of the local distribution companies in the region, the local transmitter and the IESO will follow the regional planning process to discuss opportunities to identify and meet local electricity needs. The Technical Working Group consists of staff from Kitchener-Wilmot Hydro, Alectra Utilities (Guelph), Energy+, Waterloo North Hydro, Wellington North Power, Centre Wellington Hydro, Hydro One Networks Inc. and the IESO.
An Integrated Regional Resource Plan (IRRP) was completed in April 2015 for the KWCG region that identified two transmission projects required to address needs.
The Guelph Area Transmission Refurbishment Project (GATR) was placed into service in Q4 2016 to address imminent supply needs in South-Central Guelph and the Kitchener area and to minimize the impact of potential supply interruptions to customers in Waterloo, Guelph and surrounding areas. The GATR project included the installation of two 115 kV/230 kV auto-transformers, switching facilities, and the upgrade of an existing transmission line in Guelph.
The switching facilities work was completed in October 2017 at the Galt Junction to improve supply reliability for the Cambridge‐Kitchener 230 kV Sub‐system.
